I have authored several books on fashion market, from my experience I have learnt to understand my target readers, know their interests and capitalize on the interest as the main objective of my writing.
Also, when writing, you have to remember to be simple, don't ramble so you won't distract your audience from your objective.
In addition, make your writing fun for your readers, insert relatable expressions, you can also narrate a short story from your experience but keep it in mind the goal is to communicate your objective. If you have more questions, you can give me a call.
